IMPROVEMENT IN SEPARATORS FOR THRASHlNG-MACHINES.

Specification forming part of Letters Patent No. 143,585, dated Ott'obor 14, 1873; application tilod April 21, 1873.

To all whom it may oonoora:

Do it known that l, Sonar: It. PERKINS, ot' (Iroonvillo, in tho county of Montcalm and Stato of Michigan. havo invontod at now and usot'ul l1nprovoniont in (lrain Soparators and lhrashors; and I do doolaro that the following is at truo and aoourato dosoription thoroot', rotoronoo boing had to tho aooonipanying drawings, and to tho lottors ot' rotoronoo markoll thoroon. and boing a part of this spooitioatioin in whivh- Figuro 1. shows my invontion in porspootivo. Fig. 2 is a porspootiro from tho opposito sido. Fig. 3 is a orosssootion Yortioally on tho lino .1 .z' in Fig. I. Fig. I is a porsportiro from tho roar ond ot' tho llltllllillt'. Fig. 5 is a longi tudiual \ol'tiozll sootion through tho oontor ottho maohino.

Iiiko lottors indioato lllfl parts in oaoh tiguro.

This invontion rolatos to oolnbinod thrashors and Stjltil'ilttbl's'; and oonsists, lirst, in tho oombination of a tan, a pipo having two mouths and a tubo t'or soparating tho grain from tho lightor soroonings; ainl fsooond, in. tho oombination ot' oortain cams and supports .l with a shoo, (has will bo fully dosoribod hon'inattor.

In tho aol'om alnying drawings, A roprosonts tho tood-bonoh l tho oylindor, and (J tho oonoavo, whioh may bo of" tho Ordinary construo tion. 1) ar a sorios ol' stollilorm-shapod rovolving rools, suitablyjourualod botwoon tho walls of tho maohino, and drivon by moans ot' goaring from tho main shaft Ii. F is a short grainlioanl, soourod botwoon tho two sidos of tho niaohino innnodiatoly bolow suoh of tho uppor rools as aro in tho roar ot' the siovos. (l is a shoo providoll with suitablo siovos, and is so arrangod as to roooivo a slight vibrating motion by moans of tho oams ll soourod to tho shat't l', and oporating against the roar supports J of tho shoo. Those supports aro pivotod at thoir lowor onds one to oaoh side of tho maohino, and tho shat't II roooivos motion by moans ot' a suitahlo pinion from tho goaring whioh drivos tho rools. 'lho Iowor ond of tho shoo torminatos in a box, K, whit-h oxtonds undor the whole width of the machino, and is providod with a srrmv-oarrior, which may ho drivon by any oonvoniont attaohmont. ()no ond of this box is olosod, whilo tho othor torininatos in tho vortioal. log of tho pipo Ii. tho lowor ond ot' whioh is opon. This pipo oxtolnls aoross tho top of tho inaohino, and tor- ]ninatos in two dosoonding pipos, M N. tho t'orinor ot, whioh is a spout, whilo tho lattor torlninatos in a hollow tubo, t), whioh ontors tho t'znroaso I. This t'anwaso, in whioh tho fan It rotatos, roooiving motioin by moans ot' a suitablo pinion on its shat't, from tho main shaft, is inado as noar air-tightias possiblo. 1o ooiting air only through tho hollow tubo (l.

In tho oporation of this niaohino tho grain is dolivorod from tho shoo into tho box K. and, by tho rotation of tho oonvoyor thoroin. is

oarriod and disohargod into tho Yortioal log ot' tho pipo ll, whonoo tho hoa\' f grain falls to tho ground. 'lho aotion of tho tan, drawing air as it (loos through tho hollow tubo, oroatos a Yaouuin in said pipm and tho air. rushing in from tho bottom thoroot', oarrios tho ohatl'. ohoss. and othor light inatorial up through said pipo. whonoo it is disohargod through tho spout M; a diaphragm, S, boing insortod in said pipo to provont tho ohatt from passing down through tho hollow tnbo into tho t'an.

What I. claim as my invontion and dosiro to soouro by Lottors Iatont, is

l. Tho oombination of the fan It, tho pipo I), proridod with the spouts M and N, and hollow tubo (l, all oonstructod, arrangod, and oporating substantiall as dosoribod and shown. for tho purposos sot forth.

2. Tho oombiuation of the oains IL tho roar supports .1, and tho shoc (l. oonstruotod. arrangod, and oporatod substantially as dosoribod and shown.
